The generalized integral transform called the linear canonical transform (LCT) has been designated as an emerging tool in the scenario of signal, image and video processing recently. The LCT provides a unified treatment of the generalized Fourier transforms in the sense that it is an embodiment of several well-known integral transforms including the Fourier transform, fractional Fourier transform, Fresnel transform. However, LCT has a drawback. Due to its global kernel it is not suitable for processing the signals with varying frequency content. The short-time linear canonical transform (STLCT) [1]} with a local window function overcome this drawback. For nonstationary signals STLCT has been used widely and successfully in signal separation and linear time frequency representation.
